Can I file a mechanic's lien for non payment of invoice for contract pumping of oil wells?

I am a contract pumper in Reagan County Texas. I pumped wells for Endeavor Energy for many years and was paid $12,180.00 a month for contract pumping. Endeavor sold the wells that I pumped to a company called Digital Operating Company LLC on 8-2-2022 and I pumped the wells until September 24, 2022. After I sent an invoice for September pumping on September 18, 2022 for $9000, a cut of $3,180 to try to keep my job, I was sent an email at 12:42PM on September 23, 2022 stating that they no longer needed my services and when this is completed, you will receive final payment minus expense for cleaning up your unreported spills. I made every well on the September 23, 2022 and there were no leaks or spills so I contacted the Railroad Commission to see if any leaks had been reported on any of my wells and they said no. I contacted them on several occasions about paying my invoice. On November 3, 2022 I contacted them and said, "We have been in contract with Railroad Commission and they confirmed there were no reported leaks, we are expecting payment for services provided during the month of September 2022, If we do not receive payment by November 9, 2022 we are prepared to file a Mechanic's lien again Digital Op." On November 8, 2022 at 4:28pm Leslie wrote, "We will wire you payment for 23 of 30 days of pumping services for the month of September 2022 ($6,900) tomorrow. Please provide wire instructions and we will send first thing in the morning." On November 9, 2022 at 9:14 am I replied. "Leslie, The amount being prepared for the mechanic's lien against your wells is for my invoice of $9000. I pumped these same wells for Endeavor by the month for $12,180 a month and I was forced to come down to $9000 in order to try to keep my job once your company took over. This was a $3,180 cut from what I normally charged. In lieu of the fact that you dismissed my services with out any forewarning, I expect to be paid the monthly invoice amount of $9000 as agreed upon. I work by the month, not by the day. Attached are the wiring instructions from my bank. They answered with a email threating to counter sue. As of today, nothing has been paid.
